What do you think other mentioned cities are like. Are they anything like the IRL version and what do you think Episodes set there would be like. I think that if they set an episode in Trottingham. It would have some sort of Robin Hood esque vibe to it and maybe even a pony version of the legend himself. A plot set in Manehatten could be the cutie Mark crusaders visit Babs seed and finally meet the two other members of the manehattan branch that Babs talks about in the reunion episode.
I'm not sure the ponies would like an IRL-accurate Nottingham. They'd end up wondering why half the city centre shops were shut and why the fountains have no water in them. I guess Derby could be a pony city, and maybe rams could be the occupants, like all the statues that are in the city centre.
